[0015] Figure 1 This is a schematic diagram of the overall structure of the quick disassembly tool for pin-type workpieces according to this utility model. Detailed Implementation
[0016] To make the objectives, contents, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.
[0017] This embodiment proposes a quick disassembly tool for pin-type workpieces, the structure of which is as follows: Figure 1 As shown, it mainly includes a T-shaped force-adding rod 1, a counterweight 2, and a connector. The counterweight 2 has an axial through hole machined in the middle and weighs 3 kg. The upright of the T-shaped force-adding rod 1 is inserted into the axial through hole of the counterweight 2. The bottom of the upright of the T-shaped force-adding rod 1 is provided with a thread 3, and the connector is fixedly connected to the bottom thread 3 of the T-shaped force-adding rod 1 through a central threaded hole.
[0018] When disassembling a pin-type workpiece, align the machining connector with the pin-type workpiece (such as a locating pin), manually rotate the T-shaped force bar 1 to reliably connect the connector with the locating pin, and use the counterweight 2 to strike the crossbar of the T-shaped force bar 1 upwards until the locating pin is pulled out.
[0019] This quick-release tool for pin-type workpieces has a total height of 600mm and a crossbar length of 300mm for the T-shaped extension bar. The tool is small, lightweight, and easy to carry, requiring only one person to operate. It enables rapid disassembly of large pin-type workpieces, improving repair efficiency. Various connector models are available, allowing for the use of different models depending on the specific requirements of the pin-type workpiece.
